Title: Method for preparing cyanophosphonate derivatives from pyrophosphate o r polyphosphate esters and cyanide
Inventor: VULFSON SERGEY G
IPC: C07B61/00
Filed: 1997-12-23
Abstract: Phosphorus-containing compounds such as cyanophosphonate derivatives are important precursors for the synthesis of organophosphorus compounds, which have numerous applications, for example, in herbicides, insecticides, fertilizers, flame retardants and plasticizers. Cyanophosphonate derivatives can be further converted to aminomethylphosphonate derivatives, which have been particularly important precursors in the synthesis of N-phosphonomethyglycine, a highly effective commercial herbicide (available under the trade name Roundup) useful for the control of a large variety of weeds. The syntheses of such organophosphorus compounds have commonly used a hologen derivative of phosphorus as a starting material.
Patent CA-2277027-A1 (CA)
Title: Method for measuring the attenuation in transmission lines
Inventor: BOHLEY ROLF
IPC: H04M3/26
Filed: 1999-07-08
Abstract: A method for measuring the attenuation in digital transmission lines between a switching centre and a subscriber station, with a first pulse of a known frequency spectrum being sent from the switching centre to the transmission line. From the multitude of the reflections received by the switching centre in the time domain that pulse is selected which was caused by the total reflection at the end of the line of a certain subscriber station. The frequency spectrum of the selected pulse is determined and from the frequency spectra of the outgoing pulse and the selected received pulse, the attenuation of the transmission line is determined, depending on its frequency. To achieve the extremely high dynamics necessary for this and to obtain a pulse which is free of any overshoot, reflection measuring is carried out selectively in the frequency range and the pulse is calculated per Fourier transformation. In order to reduce pulse widening by dispersion, the pulse in the frequency range is shifted to higher frequencies. The method makes it possible to qualify subscriber stations for new services by measuring the attenuation from the switching centre.

Title: Method and apparatus for detecting modified color burst signals to prevent the copying of a video program
Inventor: BRILL GEROW D
IPC: H04N5/913
Filed: 1998-03-20
Abstract: A video signal is modified so that a television receiver will provide a normal color picture but a video tape recorder will detect the modification and prohibit the video signal from being recorded. The color burst phase of the video signal is modified so as to make inferior quality pictures in the event that the resulting modified video signal is recorded. A disabling circuit (22) associated with the recorder (20) detects the presence of the modified video signal. This detection is done by determining the presence of modified color burst phase signals in even a single television line of the video signal. A  control signal (26) is produced when the modified color burst phase signal is detected, which disables the recorder (20). If no modified color burst phase signal is detected, the recorder (20) is enabled to allow an acceptable recording of the video signal.

Patent CA-2324846-A1 (CA)
Title: System and method for producing an amplified signal
Inventor: MA ZHENGXIANG
IPC: H03F3/68
Filed: 2000-10-31
Abstract: A signal amplification system involves decomposing a signal into two or more parts, amplifying the parts and then combining the amplified parts to produce the amplified signal. The decomposition can be done such that the resulting parts have characteristics that are amenable to efficient amplification. For example, decomposition of the signal to be amplified can be done using at least one threshold. The first part of the signal to be amplified can be formed by the portion of the signal within the threshold. As such, because the first part forms a signal with a lower PAR, the first part of the signal can be amplified more efficiently than the original signal. The second part of the signal can be formed by the portion of the original signal beyond the threshold. Because the second part is mostly zero, the second part can also be amplified efficiently, for example with a class C type amplifier which does not dissipate any energy when the input signal is zero.
